Famiglia

I am suspecting that some constant power source is now no longer working.

I have tested all the pins on my OBDII port, and below are the details of the test.

Can anyone tell me what their properly-working OBDII port pins test as? I assume some pin should be giving constant 12V power.

Using this diagram, I’ll explain my findings in the numbered list below.

1. Not wired.
2. Not wired.
3. Not wired.
4. Black wire (thin).
5. Black wire (thick).
6. Blue wire. Constant voltage, but only about 2 volts. Similar to #14.
7. Purple wire. Accessory power (ignition “On”), with 12 volts.
8. Green wire. Accessory power (ignition “On”), with 12 volts.
9. Not wired.
10. Not wired.
11. Not wired.
12. Not wired.
13. Not wired.
14. Pink wire. Constant voltage, but only about 2 volts.
15. Not wired.
16. Yellow wire.

Can anyone please help me with a properly-working OBDII port pins test results that I can compare against?
